Seven features by directors with a passion for Blues music.

"Musical journey" is an apt description, as Scorsese and the six other directors responsible for these seven approximately 90-minute films follow the blues--the foundation of jazz, soul, R&B, and rock & roll--from its African roots to its Mississippi Delta origins, up the river to Memphis and Chicago, then to New York, the United Kingdom, and beyond. Some of the films (like Wim Wenders's The Soul of a Man and Charles Burnett's Warming by the Devil's Fire) use extensive fictional film sequences, generally to good effect. There's also plenty of documentary footage, interviews, and contemporary studio performances recorded especially for these films. The last are among the best aspects of the DVDs, as the bonus material features the set's only complete tunes. Lou Reed's "See That My Grave Is Kept Clean" and the ElektriK Mud Kats' (with Chuck D. of Public Enemy) hip-hop-cum-traditional updating of Muddy Waters's "Mannish Boy" are among the best of them; on the other hand, a rendition of "Cry Me a River" by Lulu (?!) is a curious choice, even with Jeff Beck on hand. The absence of lengthier vintage clips, meanwhile, is the principal drawback. For that reason alone, Clint Eastwood's Piano Blues is the best of the lot; a musician himself, Eastwood simply lets the players play, which means we get extensive file footage of the likes of Art Tatum, Oscar Peterson, and Nat "King" Cole, as well as new performances by Ray Charles, Dr. John, and others. Overall, this is a set to savor, a worthwhile investment guaranteed to grow on you over the course of repeated viewings.
